before this commit: file was downloaded in xls format, which supports
maximum 256 columns and 65536 rows.
after this commit: pivot returns xlsx file when table printed and
downloaded, we have support of xlsxwriter, xlsx file supports 16384
columns and 1048576 rows

The main aim of the present refactoring is twofold:
- simplify the code that was largely complexified at the time of the
introduction of comparisons in the pivot view (Time Ranges menu),
- factorize the method expandHeader and _loadData that were too much complex.
Along the way, the pivot model structure has been simplified
and many tests have been added.
Performances in mobile mode have been improved by avoiding
unecessary operations due to useless column groupbys in that
mode.
It should now be easier to understand and modify the pivot view in future.

According to RFC 6266,
content-disposition = "Content-Disposition" ":"
disposition-type *( ";" disposition-parm )
disposition-parm can't be an empty string, and thus a ; in terminal
position is not legal, even though browsers apparently work around it.
The stdlib version of the json library is more recent than the 3.5.3
version we are pinning in `requirements.txt`
There is no reason to use it.
Closes#6940
This commit is a split of the former graphview into a pivot view (the
tabular view) and graph view (the various charts). The code was fully
rewritten.
* pivot view should be faster (better underlying data structure and
better algorithm)
* better integration with the web client (use of sidebar, of menu buttons,
bettor style)
* new feature: pivot view can be sorted
* new feature: pivot view cells can be clicked to open a list view with
the corresponding domain
* web_graph addon was removed, and the graph view code has been moved
to the addon web.
* the interaction with the searchbar was changed (no more column facet)
* better and simpler code for graph view
* mary corner cases in graph charts have been corrected (for ex, pie
chart with positive and negative numbers)
* graph/pivot correctly save their state when added to dashboard/saved
(state such as current measure, chart mode, column groupbys, ...)
